Snorkelling and diving is fun, but with the narrow view afforded by most dive masks, situational awareness and hence safety is greatly restricted. For over a decade, it has been Jon Kranhouse’s mission to revolutionize underwater vision and to perfect his designs, Kranhouse hired the same engineers NASA sought to fix the once-fuzzy Hubble Space Telescope. It worked, and Hydrooptix’ first mask lets divers have a view almost five times wider than the view available through conventional flat masks and the vision is completely distortion free, significantly improving the vision, enjoyment, safety and situational awareness of the wearer.
